THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 279,026, dated June 5, 1883.

Application filed May 1, 1883. (X0 model.) I

To It whom it may concern:

ie it known that I, XVINFIELD S. SHANA- HAN, a citizen of the United States, residing at East Chat-ham, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Thill-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain improvements in thill-couplings for vehicles, and has for its object the construction of the clip and the shaft iron in such manner that the two maybe easily and quickly connected or disconnected without the use of bolts' and nuts, as will be hereinafter particularly describedfi In the accompanying drawings, making part of this specification, Figure 1 represents a ver tical section of the clip and shaft-iron, taken in the line of draft; and Fig. 2 represents a side view with the shaft-iron detached.

In the figures, A represents the clip of a vehicle, which embraces the axle, and which is secured thereto in the usual manner.

0 represents a box, which forms a part of the clip, and which is intended for the purpose ofcarrying the end of the shaftiron. This box is provided with a horizontal annular opening, in which is inserted a cylindrical piece of rubber, E. The upper side of the box is provided with a slot, 0. The rubber E is provided with a rectangular opening, and in this opening is inserted a close-fitting case, F, which is intended to receive a bar, e, on the shaft-iron.

D represents the rear end of the shaft-iron, which is formed with two j aws, d, which embrace and fit snugly against the two sides of the box 0. Between thetwo jaws, and firmly secured to or forming a part of them, is a short bar, 0, rectangular in shape, and of such size as to fit 40 snugly in the case F.

To connect the shaft-iron to the clip it is raised, as seen in Fig. 2,to a perpendicular posi tion over the box 0, and then lowered until the two jaws embrace the sides of the box and the 4 5 bar 0 lies in the case F. NVhen the shaft-iron is then lowered so that it will assume a horizontal position, the block or rubber E and the case F make a partial revolution with the bar, 0, and a portion of the rubber closes the opening a, as seen in Fig. 1, thus excluding dirt, and at the same time holding the shaft-iron securely in place. The case F and the bar e are of such size as to fit snugly in the block E, and thethree fit so closely in the box 0 that all rattling is pre- 5 5 vented. 1 Y

The interior or opening of the box may be slightly contracted and out ofround on its front side, for binding and compressing the rubber when the iron is turned horizontally.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is r The clip A, provided with box 0, having slot a and an opening in it, in which is in- 65 cased a rubber plug, E, and metallic case F, in combination ,with the shaft-iron D and its bar 6, the several parts being constructed and connected substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
